So now that I got the new boat I need to start thinking Stereo. Basically I am not looking for top of the line but something thats sounds good. Ill probably buy all the components and have someone install. Here are my questions-----

End Result will be 6 interior speakers, 1 Sub, and 2-4 tower speakers

I have a stock kenwood deck and 6 speakers in the boat do I need a 6 channel amp or can I use a 4 channel by running 4 in parralell on two channels at a 2 ohm load and then the other two channels (bow) at the normal 4ohm level?

If doing the 2/4 ohm thing Can I get a 5 channel and do the sub on the same amp or should I get a seperate sub amp?

Thought would be a seperate amp for the tower speakers.....

Now the fun question--Amp recomendations???????Again im not looking to go professional just decent
